snrrsnrnnrne nnvionf Application filed m 12,

To. all whom it may concern Be it known that 1,, JOHN H. ANTHON, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in an Antiskidding Ueviee of which the following is a specification.

vide a new and improved device of the character described which shall be instantly available for the use without stopping the car or applying mechanical devices to the wheels.

A further object of the invention is to provide means for directing a thin stream of hot gases to the pavement direct-1y in front of the wheels of a motor vehicle in such a manner that a sufliciently high velocity will be produced which will tend to remove the major portion of moisture from said pavement and wherein the action of the heat of said gases will tend to furtherassist in removing all or a portion of the remaining. moisture to reduce skidding of said wheels on said pavement.

A still further object-is to provide flexible nozzles arranged adjacent to the wheels to direct a stream of hot gases onto the pavement, so that said nozzles may be easily and quickly deflected without injury when making contact with obstruction on the road, and also to instantly return said nozzles, by reason of their flexible nature to an operative position when moved therefrom by said contact.

Another object of the invention is to uti lize the exhaust gases and heat of the motor of said vehicle for drying the pavement in front of the wheels of the vehicle to prevent skiddin I accomplish these and other objects by means of the preferred form of the invention disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate 1921. Serial no, acacia.

similar parts throughout the, said 'specifica tion and drawings, and'in which:

Fig. l is a broken sideelevation chassis of a motor vehicle disclosing "my inn proyement applied thereto;

but;

the inside of one ofthe wheels disclosing new relative position of the nozzles to thewheels; Fig. 3 is a side elevation of Fig- 2; 1: Fig. 4 is a broken detailed view, paruy'in section disclosing the manner in which the nozzles are connected and disconnected to the exhaust manifold of the motor; and; Fig, 5 is an enlargedbroken sectional view of one ofthe nozzles disclosing-the flattenedoutlet .for increasing. the velocity ofthe stream and. for preventing the entran e of debris, a l

Referring to the drawingsithe numeral 1 i i is used to designate in general thec h'assis'of- A connection 6 is connected to the exhaust manifold at directly in'front'pf themuffler 5 and a suitable valve. 7 is provided withan arm 8 operated by a foot pedale9 to deflect the hot gases from themanifoldt into/the connection 6 before being further: expanded incthe muflier The valve? .isnor'm'allyq retained in a closedposition, .to permit the passage of said gases from said manifold 4, I

by a suitable spring 10 attached to the said.

pedal 9 and foot" board 10 said pedal9passes. t

The connection 6 is connected: to flexiblenozzles 12 having flattened andqnorma'lly through which closed ends 14 to prevent the entrance of dhris into aid-nozzles. a

The nozzles 12 are arranged withtheir ends 14 directly in front of the wheels 2 of the vehicle to project thin flat streams of hot exhaust gases directly onto the pave- Inent, said thin flat streams of gases having suflicient pressure, first, to open the flexible normally closednozzles and project a stream to comparatively high velocity directly onto thev pavement directly in front of thewheels to remove the major portion of moisture therefrom, and second, to further dry' said pavement, after said moisture has been removed therefrom, by the action of the heat of said exhausted gases.

As; the nozzles 12 are flexible and arranged close to the wheels andpavementit is obvious that when said nozzles 12 are 15. a motor vehicle having. the usualfwheels '2,- motor 3, exhaust manifo v 4pjandxmuffier struck by an obstruction on the road or pavement that said nozzles may beeasily deflected, temporarily, from their operative position Without material injury to said nozzles. it 'isalso obvious that the flexibility of said nozzles Will readily restore the same to operative position after said obstruction has become disengaged from saidnozzles.

. In operation, when a Wet, slippery pavement is encountered by the vehicle the pedal 9 is depressed. against the tension of the I spring 10 to raise the valve 7 and thereby deflect the hot exhaust gases from the exhaust-maniiold A: into the connection 6 which connection delivers said gases to the nozzles 12 before said gases are turther ere panded and cooled n the mufller 5.

It is thus obvious that the improvedv antiskidding means .is instantly available and easily and readily brought into operation Without the necessityfef stopping the vehicle of ;applying mechanical devices to the Wheels.

Byreleasing the pedal 9 the tension of i the spring 11 willlclose the valve 7 over the end of the connection 6 and the hot gases will again pass into the muffler 5.

' As hereinbeiore described thehot gases are directed by said-nozzles 12 and the ends 14; :thereof directly onto-the pavement in from the motor thereof onto a pavement and directly. in: front of and transversely to the wheels of said vehicle to remove moistureand dry said pavement by the action of heat from said gases topreventskidding of said Wheels on said pavement.

2. The combination with a motor vehicle naazooa of means for directing the exhaust gases from the motor thereol in a thin flat stream or jet and onto a pavement directly in front of and transversely to the Wheels of saidvehicle to remove moisture from said pavement by the velocity of said stream and heat from said gases to prevent skidding of said Wheels on said pavement.

3. The combination With a motor vehicle of nozzles mounted in front of the Wheels of said vehicle; and means fl er connecting said nozzles to the exhaust manifold of the motor of said vehicle whereby exhausted gases from said motor may be directed by said nozzles onto the pavement" and trans versely thereto to remove moisture l-rom said pavement and directly in front of the Wheelsof said vehicle to prevent skidding.

4:. 'ihe combinationwlth a motor vehicle of flexible nozzles mounted adjacent the Wheels of said vehicle and arranged to direct a strean's onto a pavement immediately in front of said Wheels and transversely there to; and means for connecting said nozzles With the exhaust manifold of the motor of said vehicle whereby the hot exhaustedgases from said motor may be directed by said nozzles onto the pavement directly in front or said Wheels to remove the moisture from said pavement and thereby prevent skidding.

5. The combination with a motor vehicle of flexible nozzles mounted adjacent the Wheels of said vehicle and arranged to direct a thin fiat stream onto a pavement directly in front of said Wheels and transversely thereto; and means for connecting and disconnecting said nozzleswith. the ex haust manifold of the motor of said vehicle and in advance of the muliler thereofwhere by hot exhausted gases from said motor may be'directedby said nozzles upon said pavement directly in front of said Wheels to remove the moisture from said pavement to prevent skidding of said Wheels.
